"Interesting" situation in a classroom
The network connection in one of my classrooms dropped several weeks back. As the classroom was barely used, it wasn't a high priority.
Anyway, doing the diagnostics pointed to the wall socket being faulty. That's now been resolved but I've still got no network connection in the room.
I've bunged a LAN tester on (nothing fancy, just continuity/wire order) and it shows that the cabling is fine from the plug going into the back of the PC all the way up to the plug going into the switch (i.e. all wires in the cabling connected & in the correct order). The network is Cat5e (& I use 568B wiring order everywhere if that makes a difference).
I've tried 4 different ports on 2 different switches, 2 different PCs, & new cables on either side of the run from classroom to switch, but still get no joy. No life on the NIC LEDs or the switch LEDs. Nothing. Nada. Nix. Zilch. Not a sausage.
